Kimberly A Kahle et al.
Electrophoresis, 28(17), 3024-3040 (2007-08-29)
Novel microemulsion formulations containing all chiral components are described for the enantioseparation of six pairs of pharmaceutical enantiomers (atenolol, ephedrine, metoprolol, N-methyl ephedrine, pseudoephedrine, and synephrine). The chiral surfactant dodecoxycarbonylvaline (DDCV, R- and S-), the chiral cosurfactant S-2-hexanol, and the...
D S Kalonia et al.
Journal of pharmaceutical sciences, 79(4), 364-368 (1990-04-01)
The hydrolysis kinetics of a bifunctional group compound, diethyl tartrate, was studied as a function of temperature and pH in the alkaline region. A pH-stat was used to maintain constant pH conditions in the alkaline region. This allowed the studies...
Chi-Hung Wu et al.
Electrophoresis, 28(20), 3691-3696 (2007-09-26)
A novel microemulsion based on a mixture of diethyl L-tartrate (DET) and SDS was developed for the microemulsion EKC (MEEKC) determination of structurally related steroids. The system consisted of 0.5% w/w DET, 1.7% w/w SDS, 1.2% w/w 1-butanol, 89.6% w/w...
An enantioselective total synthesis of (+)-altholactone from diethyl L-tartrate.
Somfai P.
Tetrahedron, 50(38), 11315-11320 (1994)
A new and concise synthetic route to an enantiopure (+)-conduritol-E derivative from diethyl l-tartrate.
Lee WW and Chang S.
Tetrahedron Asymmetry, 10(23), 4473-4475 (1999)
Naoki Miyakoshi et al.
The Journal of organic chemistry, 70(15), 6045-6052 (2005-07-16)
A highly stereoselective method for constructing a (2E)-methoxymethylidene-1,6-dioxaspiro[4.5]decane skeleton has been developed on the basis of the palladium(II)-catalyzed ring-closing reaction of the 3,4-dioxygenated-9-hydroxy-1-nonyn-5-one derivatives as a crucial step. The newly developed procedures could be successfully applied to the first total...
Aman Ullah et al.
Biomacromolecules, 12(10), 3826-3832 (2011-09-06)
Poultry feather quills have been extruded in a twin screw extruder with sodium sulfite treatment as a reducing agent. The effect of four different plasticizers (ethylene glycol, propylene glycol, glycerol, and diethyl tartrate) on the thermoplastic properties was then investigated....
Enantioselective total synthesis of (+)-monomorine I.
Yamazaki N and Kibayashi C.
Tetrahedron Letters, 29(45), 5767-5768 (1988)
Stereocontrolled total synthesis of the macrocyclic lactone (-)-aspicilin.
Waanders PP, et al.
Tetrahedron Letters, 28(21), 2409-2412 (1987)
Naoto Hama et al.
Organic letters, 13(4), 616-619 (2011-01-05)
A first total synthesis of broussonetine F from diethyl L-tartrate was achieved. The cornerstone of our synthesis was an orthoamide Overman rearrangement, which provided an allylic amino alcohol with complete diastereoselectivity.
Total synthesis of the light-harvesting carotenoid peridinin.
Thomas Olpp et al.
Angewandte Chemie (International ed. in English), 45(24), 4023-4027 (2006-05-10)
Jiang Weng et al.
The Journal of organic chemistry, 75(9), 3125-3128 (2010-04-17)
A short and practical synthesis of oseltamivir was accomplished in 11 steps from inexpensive and abundant diethyl D-tartrate starting material. This azide-free route featured an asymmetric aza-Henry reaction and a domino nitro-Michael/Horner-Wadsworth-Emmons (HWE) reaction as the key steps to construct...
Kimberly A Kahle et al.
Electrophoresis, 28(15), 2644-2657 (2007-06-29)
In this second study on dual-chirality microemulsions containing a chiral surfactant and a chiral oil, a less hydrophobic and lower interfacial tension chiral oil, diethyl tartrate, is employed (Part 1, Foley, J. P. et al.., Electrophoresis, DOI: 10.1002/elps.200600551). Six stereochemical...
